Gen. POLYARA, n. g.

_Mas._ _Corpus_ longiusculum. _Caput_ transversum; facies lata, plana,
non obliqua. _Palpi_ lati. _Antennae_ parvae; articulus tertius
longiconicus; arista plumosa. _Thorax_ oblongo-subquadratus. _Abdomen_
sublineare, thorace multo longinus et angustius. _Pedes_ breves, tenues.
_Alae_ latiusculae; venae optime determinatae; venae duae transversae inter
venas radialem et cubitalem; vena praebrachialis apicem versus valde
flexa.

_Male._ Body rather long. Head transverse, a little broader than the
thorax; face broad, flat, vertical. Palpi broad. Antennae small; third
joint elongate-conical, not extending more than half the length to the
epistoma; arista plumose. Thorax oblong-subquadrate. Abdomen nearly
linear, much longer and more slender than the thorax. Legs short, rather
slender; fore femora somewhat setose beneath. Wings rather broad, flat
in repose; veins very strongly marked; a transverse vein between the
cubital and mediastinal veins; two transverse veins between the radial
and cubital veins; cubital vein slightly angular between the praebrachial
transverse vein and the tip of the wing; praebrachial vein much curved
towards its tip.

The structure of the wing veins in this genus is very peculiar, and it
does not agree well with any of the established subfamilies of
_Muscidae_.

150. POLYARA INSOLITA, n. s. _Mas._ Testacea; faciei sulcis albidis;
abdomine lutescente fulvo; alis subcinereis, nigricante-fusco
submarginatis et subfasciatis.

_Male._ Testaceous, paler beneath. Facial grooves for the antennae
whitish; thorax with some almost obsolete stripes, the middle pair
approximate, slender, somewhat more distinct than the others; abdomen
somewhat lutescent-tawny; wings slightly greyish, irregularly
blackish-brown along the costa, brown at the tips, and with a brown band
which is indistinct in front but mu
